PangeaOne

I can't really address either of your concerns, because I not experienced with either with the band. But its been my experience that good or bad for you, if there is a will, there is a way.
But There is one line that you wrote that bothered me.
Here's the thing, it sounds like you are self medicating. From your statement it sounds like you rely pretty heavy on these drugs to relax,sleep,work, socialize thats a very large aspect to someones life. Have you ever thought about why? Its my guess that food for you may be another "drug" to self medicate with.
I would suggest that you talk to your doctor...most patients must have a pych exam before having the surgery. I think you might want to figure out to source as to why you "need" these druds in excess. You may benefit more from anti-depressants and Therapy.
The lap band is not like some of the other WLS, if you want to cheat , you can. It's very much a head game. It will be what you make of it. If you choose to make bad choices wheather it be in food, alcohol or drugs, you will probably not be as sucessful as someone that committs to the life style.
Good luck lemons........please consider talking to someone about your concerns/issues.
